Main digital technologies in precision farming
We briefly covered some of the different forms of technologies that are used in precision farming. FIELD MONITORING Crop Health Monitoring (mostly based on NDVI) — Normalized Difference Vegetation Index (NDVI) is a method that is used to determine the health of crops through the analysis of drone and satellite imagery. It looks at various wavelengths of light, both visible and ...

Measuring calcium in serpentine soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately measure calcium content in serpentine soils. To make ...

Soil moisture monitoring for better irrigation and crop nutrition in Cucumbers
Soil moisture monitoring is often thought of as a water saving technology. While this is true, there are other significant benefits from soil moisture monitoring. Crop nutrition is intrinsically linked to crop irrigation. Many nutrients move quickly with water or only move through plants when water is available. Nitrogen (N) is released in water and too much irrigation can result in nitrogen ...

Where is your soil water? Crop yield has the answer
Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. Quantitative determination of the maximum amount of plant-available water in soil using traditional methods on soil samples remains challenging, especially at the scale of an entire field. However, a map of plant-available water capacity for a field would be instrumental in ...

Flow4 sap flow logger from Dynamax press release
Flow4 Sap Flow Logger - Irrigation Control from Dynamax Inc (281-564-5100), is a stand-alone water balance measurement system for irrigation automation based on plant transpiration. Four Dynagage sap flow sensors read crop water consumption. These measurements are compared to rainfall, soil moisture and irrigation water supplied. The water balance or water deficit then determines the amount of ...

Crop water use efficiency
Crop water use efficiency (WUE), or yield per unit of water used, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or severe yield decline). Thus, WUE is key for agricultural production with limited water ...
